The SMC Type CQ2 Series (including CQ2B, CDQ2B, CQ2KW, etc.) is a line of space‑saving compact pneumatic cylinders designed for high‑density automation systems. Characterized by its short, low‑profile body, the CQ2 series delivers powerful output force in a minimal installation space, making it the go‑to choice for applications with tight spatial constraints.
Built to SMC’s high precision standards, the CQ2 series features a double‑acting design with optional single‑acting variants. The standard CQ2B model comes with a rubber bumper, while the CDQ2B variant is equipped with an air cushion for smoother end‑of‑stroke operation and reduced noise. Its compact structure does not compromise on rigidity, ensuring stable linear motion even under moderate lateral loads.


  • Ultra‑compact design: Short body length saves installation space, ideal for compact machinery

  • Double acting as standard; single‑acting options available (CQ2 series)

  • Air cushion / rubber bumper: CDQ2B models offer adjustable air cushion; CQ2B uses fixed bumper

  • Bore sizes: 12, 16, 20, 25, 32, 40, 50, 63, 80, 100 mm

  • High rigidity: Compact structure with stable thrust and low friction

  • Auto‑switch ready: Built‑in magnet for SMC D‑M9 series magnetic switches

  • Multiple mounting options: Square flange, foot, pin, and bracket mounts for flexible integration

  • Maintenance‑free: Non‑lubricated operation compatible with standard industrial air
